I have a piece co-authored with AEI's Kevin Hassett and Matt Jensen in the Wall Street Journal today. The article is based on a working paper we've written that looks at how other OECD countries have sought to close their fiscal gaps and which approaches have and haven't tended to succeed.

The Right Way to Balance the Budget: The experience of 21 countries over 37 years yields a simple truth: Cutting spending works, and raising taxes doesn't.

The federal debt is at its highest level since the aftermath of World War II—and it's projected to rise further. Simply stabilizing debt levels would require an immediate and permanent 23% increase in all federal tax revenues or equivalent cuts in government expenditures, according to Congressional Budget Office forecasts. What's clear is that to avoid a crisis, the federal government must undergo a significant retrenchment, or fiscal consolidation. The question is whether to do so by raising taxes or reducing government spending.

Rumors have it that President Obama will propose steps to address growing deficits in his next State of the Union address. The natural impulse of a conciliator might be to split the difference: reduce the deficit with equal parts spending cuts and tax increases. But history suggests that such an approach would be a recipe for failure.

In new research that builds on the pioneering work of Harvard economists Alberto Alesina and Silvia Ardagna, we analyzed the history of fiscal consolidations in 21 countries of the Organization for Economic Cooperation and Development over 37 years. Some of those nations repaired their fiscal problems; many did not. Our goal was to establish a detailed recipe for success. If the United States were to copy past consolidations that succeeded, what would it do?

This is an important question, because failed consolidations are more the rule than the exception. To be blunt, countries in fiscal trouble generally get there by making years of concessions to their left wing, and their fiscal consolidations tend to make too many as well. As a result, successful consolidations are rare: In only around one-fifth of cases do countries reduce their debt-to-GDP ratios by the relatively modest sum of 4.5 percentage points three years following the beginning of a consolidation. Finland from 1996 to 1998 and the United Kingdom in 1997 are two examples of successful consolidations.

The data also clearly indicate that successful attempts to balance budgets rely almost entirely on reduced government expenditures, while unsuccessful ones rely heavily on tax increases. On average, the typical unsuccessful consolidation consisted of 53% tax increases and 47% spending cuts.

By contrast, the typical successful fiscal consolidation consisted, on average, of 85% spending cuts. While tax increases play little role in successful efforts to balance budgets, there are some cases where governments reduced spending by more than was needed to lower the budget deficit, and then went on to cut taxes. Finland's consolidation in the late 1990s consisted of 108% spending cuts, accompanied by modest tax cuts.

Consistent with other studies, we found that successful consolidations focused on reducing social transfers, which in the American context means entitlements, and also on cuts to the size and pay of the government work force. A 1996 International Monetary Fund study concluded that "fiscal consolidation that concentrates on the expenditure side, and especially on transfers and government wages, is more likely to succeed in reducing the public debt ratio than tax-based consolidation." For example, in the U.K's 1997 consolidation, cuts to transfers made up 32% of expenditure cuts, and cuts to government wages made up 21%.

Likewise, a 1996 research paper by Columbia University economist Roberto Perotti concluded that "the more persistent adjustments are the ones that reduce the deficit mainly by cutting two specific types of outlays: social expenditure and the wage component of government consumption. Adjustments that do not last, by contrast, rely primarily on labor-tax increases and on capital-spending cuts."

The numbers are striking. Our research shows that the typical successful consolidation allocates 38% of the spending cuts to entitlements and 25% to reductions in government salaries. The residual comes from areas such as subsidies, infrastructure and defense.

Why is reducing entitlements and government pay so important? One explanation is that lower social transfers spur people to work and save. Reducing the government work force shifts resources to the more productive private sector.

Another reason is credibility. Governments that take on entrenched, politically sensitive spending show citizens and financial markets they are serious about fiscal responsibility.

While tax hikes slow revenue growth, policies that credibly reduce government spending in the long run boost economic growth by more than their simple effects on deficits might imply. Any attempt to address the federal government's budget shortfall that relies on less than 85% spending cuts runs too large a risk of failure. The experience of so many other countries shows that it's crucial for the U.S. to get this right.

Very interesting article and the working paper sounds quite intriguing as well! I'm surprised by the finding, mainly because my knowledge is mostly on U.S. budget policy over the last 20 or so years. Here, in the 1990s, it seems like deficit reduction was achieved primarily through tax increases, mainly the 1990 and 1993 deficit reduction efforts, though spending cuts played a role as well. I wonder was this U.S. example included in your study, and perhaps was an exception to the experiences in other countries? Or perhaps there was more to U.S. deficit reduction efforts than I am aware of, and spending cuts played a larger role than I think they did?

Thanks, Shoffy22 -- much appreciated. I'll have to check back on the US in the 1990s. I believe it's included in one of our approaches (you'd have to read the working paper to see the two different ways we did things). It may not have been included in one other approach, for the reason that we used budget data that's adjusted for the economic cycle. That's to weed out improvements in the budget that were due to the economy rather than to policy changes. I think the 1990s may in good part fall into that category and so might not have made the cut as an initial fiscal consolidation in one method we used. But I'll take a look and see.
